Description

COMPOSITION COMPRISING 2-ETHYL-1,3-HEXANEDIOL FOR USE IN A

DEODORANT SPRAY OR ANTIPERSPIRANT SPRAY

TECHNICAL FIELD

100011 The present disclosure relates to an anhydrous cosmetic composition for controlling body odour or underarm wetness, wherein the composition contains a particulate agent to combat odour or underarm wetness and a diol as solvent. The present disclosure further relates to a cosmetic product comprising the anhydrous cosmetic composition and the use of the cosmetic composition.

BACKGROUND

100021 Washing, cleaning and grooming one's body constitutes a fundamental human need.

The manufacturers of personal hygiene products are constantly trying to satisfy these human needs in many different ways. Particularly important for daily hygiene is the sustained elimination of body odour. Many body care substances designed specifically to deodorise are known from the related art and have been developed for application in regions of the body with a high density of sweat glands, particularly in the armpit region and on the feet.

100031 Body odour occurs mainly as a result of the bacterial decomposition of individual constituents of sweat on the skin. With regard to deodorising the body a rough distinction can be made between agents which already absorb or conceal unpleasant smelling substances (fragrances, perfumes), and agents which prevent the sweat from being decomposed and therewith the formation of the unpleasant smelling substances, or at least slow the process down (bacteriostatic agents, prebiotically active components and enzyme inhibitors). Depending on the mechanism chosen for preventing body odour, odour absorbers, fragrances, deodorising ion exchangers, bacteriostatic substances, prebiotically acting components, enzyme inhibitors and other active ingredients are usable as cosmetic deodorising agents. The agents must be contained in the compositions, wherein it must be guaranteed that the compositions can be delivered conveniently in a desired administration form, and that the compositions do not cause an unpleasant sensation in the skin.

[0004] The cosmetic antiperspirants used to suppress sweat that are described in the related art contain aluminium and/or zirconium compounds as sweat inhibiting agents. Firstly these sweat inhibiting compounds reduce the rate at which the body secretes sweat by temporarily constricting and/or blocking the excretory ducts of the sweat glands, with the result that the quantity of sweat can be reduced by from about 20 to about 60 percent. Secondly, because of their antimicrobial action they have an additional deodorising effect. Moreover, substances are described in the related art which can absorb the unpleasant smelling substances that have already been created. These comprise solids such as activated carbon, zinc ricinoleate, cyclodextrine or all kinds of ion exchangers.

[0005] Apart from their mechanism of action, the development of deodorants and antiperspirants is informed by their delivery form. The cosmetic products are assembled and packaged in an enormous assortment of delivery forms, for example as powder, in stick form, as aerosol spray, pump spray, liquid and gel-state roll-on application, as lotion, gel and impregnated flexible substrates (deodorant wipes). Particularly popular with consumers are sprays containing solid particles which are suspended in a liquid matrix. The matrix is often in the form of an oil phase frequently including ethers, triglycerides, ester oils or paraffin substances.

[0006] With reference to the development of sprays, product development faces two challenges. Firstly, the organic substances interfere with the release of the agents. These are often soluble in water, and the agents are prevented from dissolving in the sweat on the skin by a film of the organic substances on the agents. Secondly, the organic substances cause unwelcome deposits on textiles.

[00071 The problem the present disclosure addresses is that of providing a deodorising and/or antiperspirant composition which enables the active agent to be released more effectively.

[0008] This problem is solved by the subject-matter of embodiments described herein. A first object of the present disclosure is therefore an anhydrous cosmetic composition for controlling body odour or underarm wetness, wherein the composition contains a particulate agent to combat odour or underarm wetness and a solvent, wherein the solvent is 2-Ethy1-1,3-hexanediol.

BRIEF SUMMARY

[0009] Aspects and embodiments of the invention are defined in the appended claims.

DETAILED DESCRIPTION

[0010] The following detailed description is merely exemplary in nature and is not intended to limit the disclosure or the application and uses of the subject matter as described herein. Furthermore, there is no intention to be bound by any theory presented in the preceding background or the following detailed description.

100111 Surprisingly it was found that 2-Ethyl-1,3-hexanediol is particularly effective in improving the release of the agent. Moreover, it is possible for the quantity of silicone oils at issue to be reduced and/or their use to be avoided entirely by replacing some of the organic carrier typically used or the entirety thereof with the special solvent [0012] The compositions as contemplated herein should be anhydrous, in particular substantially anhydrous. The person skilled in the art understands an anhydrous composition to be a composition to which no water is added. Given the fact that raw materials generally -and with regard to the present disclosure particularly the particulate agents -are not completely free of water, the composition as contemplated herein contains water in a small quantity. Moreover, products always absorb a certain amount of moisture. A preferred composition as contemplated herein is substantially free of water. The cosmetic preparation comprises preferably from about 0 to about 3 wt%, more preferably from about 0.1 to about 2 wt%, most preferably from about 0.2 to about 1 wt% water, relative to the total weight of the composition.

[0013] It may be assumed that the improved release of the particulate agent or particulate agents is correlated with the combination of the solubility of the solvent in water and its capability to disperse the particulate agents. For this reason, preferred particulate agents are the object of preferred embodiments.

[0014] According to a preferred embodiment of the present disclosure, the particulate agent against underarm wetness is an aluminium salt, a zirconium salt, a zinc salt, an aluminium/zirconium mixed salt, preferably aluminium chlorohydrate, aluminium-zirconiumchlorohydrate, zinc chloride, zinc sulfocarbolate, zinc sulfate, zirconium chlorohydrate, aluminium-zirconium-chlorohydrate-glycine complexes, silver or a silver salt, in particular activated aluminium chlorohydrate. Further particularly preferred particulate agents based on silver salts include silver citrate, silver dihydrogen citrate, silver lactate and silver sulfate, soluble complex salts of silver, colloidal silver and silver zeolites.

[0015] The object of embodiments of the present invention is to be understood to mean that the composition comprises either an agent against underarm wetness or an agent against odour or both. According to a preferred embodiment, the composition also contains a particulate agent against odour as well as or instead of the particulate agent against underarm wetness. According to a preferred embodiment of the present disclosure, the composition comprises a particulate agent against odour which includes one or more of the following: cyclodextrine, zeolites, metal carbonates, preferably zinc carbonate, calcium carbonate, or magnesium carbonate, metal hydroxides, preferably magnesium hydroxide, metal hydrogen carbonates, preferably sodium bicarbonate, mixed salts of alkaline-earth metal hydroxides and alkaline-earth metal carbonate, zinc chloride hydroxide, diatoms, silicates, preferably aluminium silicates, calcium silicate, magnesium -aluminium metasili cate, magnesium-aluminium si1icate, sodium-aluminium silicates, magnesium-calcium silicates, or magnesium silicate, silicas, starch or derivatives thereof, aluminium or sodium salts of starch esterified with octenyl succinic anhydride, modified cornstarch, glyceryl starch, amylodextrin, maltodextrin, bentonite, silica, hectorite, kaolin, montmorillonite, perlite, talcum or mixtures of any of the aforementioned, most particularly preferably sodium bicarbonate [0016] As was noted above, the solvent 2-Ethyl-1,3-hexanediol serves as a substitute for carriers that are usually used, wherein however it is also possible that only a part of the organic solvents usually used is replaced According to a preferred embodiment, the composition is based on an organic carrier which is a cosmetic oil comprising liquid paraffin oil or isoparaffin oil, preferably i sodecane, i soundecane, i sododecane, i sotridecane, i sotetradecane, isopentadecane, isohexadecane or isoeicosane, esters of linear or branched saturated or unsaturated C2-30 fatty alcohols with linear or branched saturated or unsaturated C2-30 fatty acids, C8-C22 fatty alcohol esters of monovalent or polyvalent C2-C7 hydroxycarboxylic acids, triethyl citrate, branched saturated or unsaturated C6-30 fatty alcohols, mono-, di-and triglycerides of linear or branched saturated or unsaturated, optionally hydroxylated C8-30 fatty acids, dicarboxylic acid esters of linear or branched C2-C10 alkanols, adducts of ethylene oxide and/or propylene oxide with mono-or polyvalent C3-22 alkanols, linear silicone oils, cyclic silicone oils, particularly cyclopentasiloxane, polypropylene glycol ether, polyethylene glycol ether, organic esters -particularly esters of the glycerins, ethers and ether carbonates as well as mixtures of one or more of the above.

100171 According to a preferred embodiment, the composition as contemplated herein contains a thickener to improve the composition's manageability. The thickener is preferably adjusted to the solvent. According to a preferred embodiment of the present disclosure, the composition contains a thickener which is preferably selected from the group including hydrophobically modified clay minerals, hydrophobically modified amorphous silicon dioxide, hydrophilic amorphous silicon dioxide, bentone gels, Versagel types and dextrin esters.

[0018] According to a preferred embodiment of the present disclosure, the hydrophobically modified amorphous silicon dioxide is a product of silylation from a reaction between a precipitated silicic acid and/or a pyrogenic silicic acid and an organosilicon compound, wherein the organosilicon compound is preferably an alkyl siloxane, a silane, preferably trimethylsilane, or a silazane, in particular hexamethyl disilazane.

More preferably still, the hydrophobically modified amorphous silicon dioxide is Silica Silylate (INCI), Silica Cetyl Silylate (INCI) or Silica Dimethyl Silylate (INCI). The hydrophobically modified amorphous silicon dioxide is rendered hydrophobic by the alkyl groups of the organosilicon compound. After hydrophobisation, the alkyl groups are located on the surface of the silicon dioxide particles. The number of carbon atoms in the alkyl group influences the degree of hydrophobisation. Silica Silylate (INCI), Silica Cetyl Silylate (INCI) and Silica Dimethyl Silylate (INCI) are products which are available commercially. Aerosil R 812 S is a preferred example of such.

100191 Phyllosilicates may also be used as thickeners as an alternative to the hydrophobic silicic acids.

In this preferred embodiment, further components may also be contained in the composition. Accordingly, if an exemplary composition contains about 10 wt% solvent, about 2 wt% thickener, about 60 wt% of a cosmetic oil and about 20 wt% sodium bicarbonate, further components are included in order to reach about 100 wt% of the composition.

[0022] The advantage effect of wetness reduction is particularly pronounced with the addition of 2-Ethyl-1,3-hexanediol, in particular addition thereof in a quantity from about 5 to about 20 wt%.

[0023] Further preferred deodorant additives are selected from "prebiotically active components", which as contemplated herein are understood to include those components which inhibit only or at least mainly the odour-producing microbes of the skin microtlora, arid not the desirable microbes, that is to say those which do not produce odour and which are part of a healthy skin microflora. Agents such as conifer extracts, in particular from the group of Pinaceae, and plant extracts from the group of Sapindaceae, Araliaceae, Lamiaceae and Saxifragaceae, particularly extracts of Picea spp, Paullinia sp, Panax sp., Lamium album or Ribes nigrum and mixtures of said substances are named explicitly here [0024] Further preferred deodorant additives are selected from the perfume oils and Deosafe® perfume oils with bacteriostatic effect which are available commercially from the Symri se company, formerly Flaarmann und Reimer.
